Thank you all for your great tips! I really appreciate it! We'll be crossing the border at Sarnia this Saturday so I'm hoping that traffic won't be too bad. DH found that it's faster this way instead of going through Detroit/Windsor. Yes, we'll be staying on the Canadian side of the Falls...were originally planning on going on Monday, but may go on Tuesday instead because of the holiday. As for Ontario Place, I have great memories from my childhood. I noticed on their website that there's a lot of water activities for kids. Is it worth going to if the weather isn't warm enough for a swimsuit?
